Kamen Rider 1
He was revived to combat an opposing faction Nova Shocker while trying to release Alexander the Great Gamma Eyecon from the body of Tobei Tachibana's granddaughter, Mayu, to obtain its power. However, his faction is still overpowered by Shocker Nova's strength, leading him to make an uneasy alliance with the Kamen Riders Ghost, Specter, and a newly improved Kamen Rider 1. Though he still has unfinished business with Takeshi Hongo, Takeshi Hongo refused to fight him, due to his injuries caused by Urga Alexander, leaving Ambassador Hell to die instead.
- Ambassador Hell was based on Big Machine, a villain from the Kamen Rider manga by Shotaro Ishinomori, though unlike Big Machine Hell was a high-ranking executive and not the leader of Shocker and his design was modified to have a human face.
